Application filed January 12, 1922. Serial No. 528,727.

T 0 all whom it may concern:

Be it known that I, WALTER P. Osooon,, a citizen of the United States,and resident of Malden, county of Middlesex, State of Massachusetts,have invented an Improvement in Taping Machines, of which the followingdescriptiomin connection with the accompanying drawing, is aspecification, like characters on the drawing representing like parts.

This invention relates to a machine for applying tape to sheet material.A machine for this purpose is capable of a wide use wherever it isdesired to apply a strip of tape .to sheet material, but is speciallyuseful in the shoe industryfor applying a strip of tape to the differentparts of the upper of a shoe.

In the'manufacture of shoes it is a com mon practice to thus apply tapeto the shoe uppers, sometimes for the purpose of rein forcing the edgeof quarters, Vamps, etc., and sometimes for the purpose of covering thelining directly beneath the perforations formed in the upper forornamental purposes to prevent the lining from showing through theperforations. In the latter case the tape is applied to the inside ofthe upper so as to cover the perforations, the tape usually being of thesame colc r as the upper.

One of the objects of my invention is to provide a taping machine whichis constructed so that the tape may be applied asreadily on a curve asin a straight line.

Another object of the invention is to provide an improved taping machinein which the tape may be readily applied in a reverse curve as well asalong a line which curves in one direction only.

Another feature of my invention relates to a. novel taping machine bywhich when p the tape is applied along-a curved line the portion of thetape on the inner edge of the curve will be gathere l and flattenedagainst the work. 7

Still another feature of they invention relates to a. novel means fordelivering .the tape to the tape-applying mechanism free from tension sothat as the tape is applied P to the work it is. subjected only to thetension given to it by the tape-applying means. Still another object ofthe invention is to provide an improved taping machine whichv isadaptedto apply the tape either by a.

so-called cold process or by a so-called hot process? In the'coldprocess the tape is drawn through a cement container provided with asuitable cement so that when the tape is delivered to the work it willbe cement-coated' and will thus be caused to adhere to the work. In thehot process the tape has been previously provided on one,

face with a cement-i'tious-coating which is of such a nature that it isnormally hard tape sufficiently to cause the tape to adhere to the work.i

Still-another object of the invention is to provide a novel machine .ofthis type in which the work is fed forward by the move ment of thepresser member. For this pur-- pose the presser element has anoscillating motion in addition to its movement toward and from the work,these combined movements operating to bring the presser member againstthe workto press the'tape thereto and then causing the member to have arocking movement as well as a forward movement which result-s in feedingthe work i and at the same time pressing the tape to the work with arocking movement.

Still otherfobjects of my invention are to improve generally tapingmachines in particulars which will be more fully hereinafterset forth.

In order to give an understanding of the invention I have illustrated inthe drawings a selected embodiment thereof which will now be describedafter which the novel features will be pointed out in the appendedclaims.

mechanism showing the parts in diti'erent positions from what isillustrated in Figs. 1 and 2.

Fig. 10 is a perspective view of the work uide. iFig. 11 is a section onthe line 11-11,

is stated above this machine is adapted to apply an adhesive-coated tapeor strip to sheet material. For instance in Fig. 7 I have shown at 1 apiece of sheet material to which the tape strip 2 is applied, said striphaving on its under face a coating of adhesive material so as to causeit to adhere to the work 1 when it is pressed thereagainst. In said Fig.7 the work 1 is shown as provided with a row of perforations 3 and thetape strip 2 is applied to the work so as to cover these perforations.This tape strip, however, might be applied to the edge or any otherportion of the work for reinforcing it.

The applying of the tape strip to sheet material to cover perforationsis frequently resorted to in the manufacture of shoes where the shoeupper is formed with rows of perforations for ornamental purposes and insuch case it is desirable to cover the lining so that the latter willnot show through the perforations after the shoe is completed. For thispurpose the tape strip 2 is applied to the inner face of the upper alongthe line of perforations thereby preventing the lining from beingvisible through the perforations.

The taping machine herein shown comprises a work support preferably inthe orm of aroll, over which the sheet material is fed, means for layinga tape strip on the sheet material as it is fed, a hammer or pressermember to press the tape against the sheet material and to feed thelatter, and means for drawing the tape from a source of supply anddelivering it free from tension to the tape-applying means.

This hammer or presser element has a movement toward and from the rolland it also has an oscillating movement which serves to feed the workforward and also to give the presser member a rolling contact with thetape during the pressing operation. 1 The operative parts of the machineare carried by a suitable frame 4 which may have any desirable shape butwill preferably be a shape so that it can be placed on a bench or table.The work-support, which as stated above is preferably in the form of aroll is shown at 5 as mounted for rotation upon a shaft 6 carried by aslide 7 supported in a suitable base 8, the slide belng acted upon by aspring 9 so that the work supportis yieldingly supported. The

tape strip 2 1s delivered to the work 1 as it passes over the roll 5through a tapegu d ng device herein shown as a curved guldlng member 10.over which the tape passes and a tension foot 11 resting on the tapeand holding it against the guiding member 10 in a manner to apply asubstantially uniform tension thereto. Said guiding member is shown ashaving ears 12 at its sides between which the tape passes and whichretains the tape in its proper path. The tape is thus fed between thetension foot 11 and the guiding member 10 and is delivered to the workfrom these parts. The tension foot 11 is yieldingly held against thetape as will be presently described. The tape is pressed against thework thereby to cause it to adhere thereto by means of a presser member13, which is in the form of a block having a convexly curved face 14,the curvature of which is slightly greater than that of the roll 5.

This presser member has a reciprocating movement toward and from thework and also has an oscillating movement, the construction being suchthat the face 14: of the presser member has an advance rocking movementon the tape while it is in contact therewith, such rocking movementeffectively pressing the tape against the work and also feeding the workand tape forwardly. Said member is,

The operative parts of the machine are actuated from adriving shaft 15journalled in the frame 4 and actuated from any suitable source ofpower. The presser member 13 is carried by an oscillating head 16, the

latter having an extension 17 thereon provided with a portion 18 thatencircles an eccentric 19 fast on the shaft 15. This head 16 oscillatesabout a stud 20 fast in the frame 4. The head 16 is shown as providedwith a vertical slot 21in which is received a block 22 that is pivotedto the stud 20. This slot construction allows the head 16 to rise andfall with the movement of the eccentric 19 and the stud 20 furnishes thecenter about which it oscillates. The presser member 13 will thus havean oscillatory movement in an elliptical orbit and as the shaft rotatesin the direction of the arrow Figs. 1 and 2 it will be seen that whenthe eccentric is passing over the lower center the presser member 13will be in contact with the tape and will be moving to the left Figs. 1and 2 thus giving a feeding movement, while when the eccentric ispassing over the upper center the presser member will be elevated fromthe work and will be moving towards the right Figs. 1 and 2.

The curved face 14 of the presser member will thus have a rockingadvance movement while it is in engagement with the tape and thismovement serves not only to ress the tape against the work for aconsiderablelength but also feeds the work forward. The extent of eachfeeding movement is,

therefore, a combmed presser and feed member.

movement, and, therefore. there will be a more or less overlappingaction between successive rocking movements so that any part of the tapeis subjected to two pressing operations. v j

The tape 2 is drawn from a source of supply, not shown, and then passesthrouglr a tape pull-oif mechanism which withdraws the tape from thesource of supply and delivers itto the tape-applying device, and fromthe pull-ofi' mechanism the tape passes over a pulley or roll 23 pivotedat 2% on an arm extending from the frame 4, and from'this roll the tapepasses to a curved tape-guiding member 26 which leads it to the deliveryguide 10.

The tension foot-"11 is shown as carried on the lower end of an arm 260pivoted to a pin 27 carried in a forked support 28 that is secured to aboss 29 formed on the frame. For this purpose the support 28 is providedwith a stem 30 which extends through the. boss and said stem is held inadjusted position by a set screw 31. The tension foot has integraltherewith a finger piece 32 which is acted upon by. a spring 33 thatyieldingly holds the tension against the .tape. ,Nhen the finger piece32is depressed the tension foot is elevated from the work;

The tape pull-off mechanism is constructed to positively draw the tapeintermittently from a source'of supply and then to deliver the tape sodrawn to the roll 23. The

- tape extends from the source of supply around the guide pins 34, 35fast in a yoke member 36 .secured to the frame 4, thence passes over areciprocating pull-ofi' stud 37 and thence passes over fixed guide pins.38, 39 also carried by the yoke 36 and thence passes to thedirectionroll 23. The pull-oil stud 37 is secured to the portion 17. of theheadand therefore has arising and falling movement. "During the risingmovement it draws a-loop of tape upwardly between the guide studs 35, 38thus pulling tape from the source of supply, and during its downwardmovement it gives up the tape thus pulled otf from the source of supplyand a take up arm 40 acts on the tape to deliver the slack to the roll23. This take up arm is shown as pivoted'on the stud 37 and it isprovided at its end with a 'stud 41 to act on the tape between the stud39 and the roll 33. Said take up arm is actuated at proper times by acam 42 fast on the shaft-.15 and it is held against the cam by a returnspring 43. The cam operates to give the take up arm repeated downwardswinging movements into the position shown in Fig. 8.

In order to better control the feeding movement of the tape I haveprovided a gripping device which co-operates with the other.

take up arm will advance the slack in the loop llto the roll 23. Thisgripping device comprises two gripping members 45, -16 pivoted to theblock 22 at 47 and 48 respectively. Each gripping device is providedwith a curved serrated gripping face 49 and a spring 50 is placedbetween them which tends to sep rate them from each The block 22 carriesstop screws' 51 which limit the separating movement of the grippingmembers.

hen the eccentricis passing over the low center into the position shownin Fig. 2 the oscillating movement of the-block 22 will carry thegripping member 46 against'the tapethat passes over the stud 38 therebygripping the tape at this point. The rising movement of the head 16 andpull-off pin 37 will elongate the loop44 of tape and because the tape isgripped against the pin 38 the amount'of tape necessary for elongatingthe loop will be drawn from the source of supply. When the eccentricpasses over the top center as shown in Fig. 9 then the head 16 is swungtobring the gripping member 45 to, give up slack in the loop -14 the cam42 acts on the take up arm 40 and draws this slack over the pin39 to theroll 23.

The length of ta between the roll 23 and the approach gui e 10 is,.therefore, relatively free from tension, and as'the tape is fed to thework from the guide 10the tension foot 11 applies the requisite lighttention thereto which is desirable to properlyattach the tape to thework. a In addition to the'above features my invention also contemplates1 a' construction which facilitates the applying of the tape along acurved line. Thisis done by means which takes care of the fullness onthe inside edge of the tape on the curve, either by .flattening suchfullness or by permitting it to form into plaits or folds which arepressed against the work so that they are hardly visible. v

apply the tape rapidly along any edge contour or along any desiredlinewithout the necessity of stopping the machine in passing around cornersto adjust the tape 'for the curve. In my "invention the tape isautomatically adjusted to fit the curve as the work is fed. This isillustrated in Fig. 7 wherein the line of perforations 3 which is to becovered by the tape 2 is formed on a curve. In feeding work of this typethrough tions will be fed beneath the tape-applying means. My improvedmechanism is constructed so that at each forward ste of the work a humpor loop 52 is forme in the tape on the inside of the curve immediatelyin front of the tension foot, and when the presser member 13 acts on thehumped tape, the hump or loop will be eitherflattened out or will befolded over against-the body of the tape, as shown at. 53 in Fig. 17,depend-. ing upon the character of the tape. If'the tape is a light,very flexible tape, it will be flattened out but if the tape is thickerand stiffer it will probably be formed into the fold or plait. The tapewill thus be laid without stretching the edge on the outside of thecurve and by merely gathering the tape on the inside edge.

This result is secured by the employment of a pair of pivot fingers 54which are pivotally mounted on the stud 27 and which are supported onthe work at the marginal portions of the tape in front of the tensionfoot.' These fingers are acted upon by springs which yieldingly holdthem against the work and the endsof the fingers operate in slots formedin the presser member 13 so that the fingers are engaging the work atthe point where the presser member operates thereon. So long as the tapeis being laid along a straight line it will be fed under the fingers andthey will simply act to prevent retrograde'movement of the tape or work.

During the operation of laying the tape along a curve such as shown inFig. 7, the work will be fed forward .one step while it is acted upon bythe presser member 13, and when-the presser member is raised from thework then the operator turns orswerves the work more or less dependingon the sharpness of the curve. During this turnmg movement of the workit will pivot on the finger 54 at the outer edge of the curve and.thetape between the fingers 54' and thetension foot 11 will be formedinto a hump or loop, as shown at 52, Fig. 7. The hump or loop thus madeat the inner edge of the curve has a conical form developmg from theouter edge of the curve. 'When the presser member 13 is'brought downagainst the work it flattens out this hump 52 either with or withoutforming a fold or lait 53 depending upon the character of t e tape.

and the sharpness of the curve, lVhen the presser member 13 is againraised then the work will again. be turned or swerved slightly on thefinger 54 on the outside of thetape as a pivot due 'to the pressure ofthe operators hand, and another hump will be formed between the fingersand the ten-'.

- sion. foot, said hump being pressed down or flattened out ,by thepresser "member at its next descent. This operation is repeated cleararound the curve and is as perfect on a sharp curve as on a gradual one,the only difference being that on a sharp curve the plaits will be widerthan on a gradual curve.v If the curve is in the reverse direction oraway from the operator, then the work will pivot on the pivot finger 54nearest the observer, but otherwise the operationswill be as abovedescribed.

" Vhere the curve is a very abrupt one it i is sometimes desirable torelieve the pivot finger 54 on the inside of the curve of its springpressure and I have provided for this herein by means of a cam member 56which is fast on the stud 27, the latter being provided with a fingerpiece 57 by which it may be turned. This shaft has two cams 56 thereon,one for-acting on each of, the springs 55 and said springs are formedwith the wing portions 58 to be engaged by the cams. The high points ofthe two cams 56 are situated apart so that when the shaft 27 is turnedin one direction one spring 5-5 willbe rendered inac tive and when theshaft is turned through 90 the other spring will be rendered inactive.The shaft 27 may also be turned so that neither cam will be operativeand, therefore, both springs will be active; During thelayingof tapealong a straight line the shaft will be effective but when the tape isbeing laid on a sharp or abrupt curve then the shaft 27 will be turnedto render one or the other of the fingers 54 inoperative depending onthe direction of the curve.

It will be noted that the face of the hammer or presser member 13 has. aconsiderable extent longitudinally of the tape. In

27 is situated so that both springs fact the extent of this face is-morethan the distance which the tape is fed at each ste so that each part ofthe tape will be acted on a plurality of times by the hammer 'or pressermember; The'advantage of this'is to i ure-that the tape will be firmly'pressed against. and caused to adhere to the work 1. a

As the face 14 moves forwardly the work isfed and a new length ofunattached tape isfed into the space in advance of the tenthe nextdownward movement of the presser member 13 so that the feeding movement,of

the presser member operates not only to guide in the form ofa guidemember 99 to engage the edge of the work as shown in Fig. 6. This guidemember 99' is adjustabl carried on an arm 98 having a hub 97 whic .sionfoot to be applied to the work upon is mounted on a stud 96. The purposeof thus mounting the guide is to permit .it to be moved into and out ofoperative position.

'hen it is desired to use the guide it is thrown into the position shownin Fig. 6, but when it is not desired to use said guide it can be swungdown.

This guide member is yieldingly held in its operative position by meansof a tooth or projection 9-1 carried by the frame entering a. notch orprojection 95 formed in the hub 97. a spring 93 serving to hold thetooth yieldingly in the notch. The notch -can be readily disengaged fromthe tooth,

however. when it is desired to swing the guide into its inoperativeposition.
